Automatic Thumbnail Creator Not Working

[Guest]

Anyone use the automatic Thumbnail creator? I have installed the code without error but it doesnt work. Is this script supposed to create the folder "imagecache" or do i create it manually? In any case I have tried doing both and no images appear in this folder. Anyone else have this problem??

 

 

Here is the instruction file that came with this modification...

 

 

 

This is an automatic Thumbnail creator.

Each picture in your Shop will be chached in the "/catalog/images/imagecache" directory in the right

size and with the same name as the original.

The size is set in the Admin panel under Configuration - Images.

These values are the max values. The thumbnail will be created in the right proportions.

 

The tumbnail will be created an th first time the picture is call in the Shop.

Once an thumbnail is created it will always be used until you change the size in the Admin panel.

 

If you delete an image, you have also to delete the thumbnail in the "/catalog/images/imagecache" directory manually

 

Have fun!

 

 

Installing should be quite easy, only one file tho change.

Follow these 7 steps:

 

 

 

1. Open the File: /catalog/includes/functions/html_output.php

 

2. Search for: (~ Line 73)

////

// The HTML image wrapper function

function tep_image($src, $alt = '', $width = '', $height = '', $params = '') {

if ( (($src == '') || ($src == DIR_WS_IMAGES)) && (IMAGE_REQUIRED == 'false') ) {

return '';

}

 

3. Insert the following after it:

 

 

if ($image_size = @getimagesize($src)) {

if ((CONFIG_CALCULATE_IMAGE_SIZE == 'true')) {

if ( ($width) || ($height) ) {

if ( $width=="100%" ) {

$width = $image_size[0];

} elseif ( $height=="100%" ) {

$height = $image_size[1];

} elseif ( $width==0 ) {

unset($width);

} elseif ( $height==0 ) {

unset($height);

}

$src=thumbimage(DIR_FS_CATALOG . '/' .$src, $width, $height, 1, 1, DIR_FS_CATALOG . '/' . DIR_WS_IMAGES . 'imagecache');

if ((($image_size[1]/$height) > ($image_size[0]/$width) ) && $height>0){

$width=ceil(($image_size[0]/$image_size[1])* $height);

} elseif ($width>0) {

$height=ceil($width/($image_size[0]/$image_size[1]));

}

}

}

} elseif (IMAGE_REQUIRED == 'false') {

return '';

}

 

 

4. Search for this and delete it:

 

if ( (CONFIG_CALCULATE_IMAGE_SIZE == 'true') && (empty($width) || empty($height)) ) {

if ($image_size = @getimagesize($src)) {

if (empty($width) && tep_not_null($height)) {

$ratio = $height / $image_size[1];

$width = $image_size[0] * $ratio;

} elseif (tep_not_null($width) && empty($height)) {

$ratio = $width / $image_size[0];

$height = $image_size[1] * $ratio;

} elseif (empty($width) && empty($height)) {

$width = $image_size[0];

$height = $image_size[1];

}

} elseif (IMAGE_REQUIRED == 'false') {

return false;

}

}

 

 

 

5. Go to the bottom of the File and insert before the ?>

if your Webspace has GIF read and write ability delete GIF in the following text at $not_supported_formats = array ("GIF"); // Write in capital Letters!!

 

 

function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){
